My Miyasama trident has a lot of flowers that overnight turned to the winged keys or seeds.They are still green right now . Do they turn brown and naturally fall off like our regular maples? IS that the best time to plant them? How deep ? Im excited abot this because the damn plant I have was bought sight unseen and has a terrible shape. An almost 90 degree sharp bend about 2 inches above soil line on the main trunk with 2 other trunks coming up ok.Ive set an air layer just above the bend but so far I don't see any roots in the sphagnum moss. Another weird thing is that this tree shows no leaves ! Just different type of leafy structure with the flowers. Im on Long Island,NY zone 7a and its May 29 ,so shouldnt it have real leaves???
